TitleUnpublished letter, regarding a safety lamp from Eugene du Mesnil to the Royal Society
Date30 August 1839
DescriptionDu Mesnil describes a safety lamp he invented in December 1834, which he believes will be 'very invaluable' to colliers. He explains how the safety of the lamp depends entirely on its proportions. Du Mesnil's lamp can be burnt without snuffing for 14 hours, is not easily broken, and will 'make a loud noise in the case of a danger'.
